for deviantart, it seems to break the website as it doesn't register mouse clicks UNLESS you whitelist the site. there may be more sites out there like this but personally, this is the only one i experienced.

In general it blocks popup for good but unfortunatelly many websites implement this notification in the way that without confirmation it's impossible to browse or website seems cripled. That's why I need to disable.

It doesn't work on some websites.

works nice when it does, but other times it completely breaks sites :(

this addon was great, but avast lol... thanks for informing us Daniel, please guys propose alternatives in reviews ;)

Please publish your source code on GitHub. It's already licensed under GPLv3 and having easy access to the source code would make it possible for the community to make contributions and improve the extension. Functionality wise, top notch - I couldn't imagine using the internet without it <3

I have always been satisfied with this supplement and I have used it for many years. Recently, however, it has begun to negatively affect the behavior of Firefox by the fact that, for example, on the website www.czc.cz it was not possible to scroll the page down. I had to remove the add-on and now use Ninja Cookie to block cookie dialogs.

I had to disabled it, too many (italian) websites were broken by it (e.g. www.radio24.ilsole24ore.com)

As of November of 2021, I ("technical data-security" person in public sector) see the legal situation for this addon as follows:

Lets start with a big con about entering legal contracts by surfing in the world wide web:

- Absolutely violates the " informed consent" required by GDPR by sometimes giving consent but hiding what I actually agreed to. Legally, neither the user nor the website now know if anyone is at fault for aggregating and using personal data. I can neither exercise my rights to be informed or correct data that was collected, nor can the website owner use or sell my data in good conscience.

- The developers website acknowledges this schism: "Please educate yourself about cookie related privacy issues and ways to protect yourself and your data. For example, you can block 3rd party cookies, install ad blocking extensions and then block tracking tools, delete browsing data regularly, enable Tracking Protection in your browser etc."
Which is the right way to handle cookie banners. This is the worst way for all parties involved. To reiterate: even the website owners get a poisoned gift by receiving non-legally-valid consent, and the user waives all control over their personal rights without even knowing, how that might hurt him or her whenever this add-on allows some tracking cookies to be stored.

Pros:

+ Visually, seems to work. (Legally, see above. Browser Cookies are not about cookies or computer science, but the actual subject matter is keeping others from knowing what kind of stigmatised interests or ridiculed condition you keep to yourself or a very limited audience. By not caring, you shoot yourself in the foot.)
+ The developer actually reads this and reacts to it.

UPDATE:

Starting in December, this Addon will probably need to register as a "Personal Information Management Systems" (PIMS) in germany, to finally become legal. Let's hope that it won't be an extensive and thereby expensive certification. If @Kiko fails to do that, this app will still work ins legally gray area are finally become illegal in germany and should regionally be blocked to avoid anyone sueing Kiko or the end-users.

The EUs info on that:

This might even of interest for power users or people who actually read EULAs.

Was ist mit youtube?? es funktioniert seit wochen nicht mehr. wann kommt ein update?

Extension does as advertised. \(^-^)/

Was reluctant to use the extension at first, given it may blindly accept more cookies than I want. However, given the broad selection of other cookie blocking extensions available, I don't think this is a significant issue.

Since the Avast aquisition, some users have opted to fork the project. The fork aims to put the community interest first, like allowing contributions. So I've since uninstalled this extension and installed "I still don't care about cookies" instead.

Any chance this add-on is slated for review by Firefox to receive "verified" or a higher status?

The Cookies are just automatically beeing accepted and thats the reason why the warnings are not supposed to be shown
I hoped that not only the cookie warnings would not be shown, but especially that these will not be accepted. That should be the point

Works fine but injects random text into the html tag and doesn't explain why. Not suggesting this is malware, probably for some type of cookiewall, but I would like to see this explained somewhere and not have my DOM messed with.

-edit- Can't reply as far as I know. It definitely is this extension. Check common.js and common8.js.

The EU regulation which many people criticize in these comments are a true progress in your own liberty and rights. I agree to said that the implementation is really bad on most of websites and there is something to do. But take the time to read carefully what is RGPD and what is changing with this regulation and you will see that it has been made for you, to protect you.
For the author, you really should precise what does it mean "I don't care about cookies" , does it mean that it click by default on "accept all" or "reject all". I think that it matter for all the users of this extension that probably (for some of them) take care to their privacy...

Not available on Firefox for Android.
